SASH-FASTENER.'

SPECIFICATION forming part of Letters Patent No. 410,382, dated September 3, 1889.

Application iiled April 26, 1889. Serial No. 308,710. (No model.)

To all whom it may concern:

Be it known that I, HARRISON Srnoes, of Valencia,in the county of Shawnee and State of Kansas, have invented a new and useful Improvement in. Vindow-Sash Fasteners, of which the following is a full, clear, and exact description.

My invention relates to an improvement in window-sash fasteners, and has for its object to provide a device capable of serving as a substitute for the weight and pulley ordinarily employed in connection with window-sashes,

and to so construct the said devicethat it will be very simple and durable and readily and expeditiously manipulated.

A further object of the invention is to provide a device by the use of which the upper and lower sashes may be raised or lowered any desired distance and locked at any desired point, and also to provide a device Vcapable of attachment to any adjustable windowsash. v

The invention consists in the novel construction and combination of the several part-s, as will be hereinafter morefully set forth, and pointed out in the claims.

Reference is to be had to the accompau ying drawings, forming a part of this specification, in which similar iigures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of a windowframe containing a window-sash provided with my improvement. Fig. 2 is a central vertical section through the frame and window-sashes, and Fig. 3 is a vertical enlarged section through a portion of the lower sash and one section of the device carried by the same.

The window-frame 10 may be of any approved construction; likewise the upper and lower sashes ll and 12.

Upon the front or inner face of the central vertical rail 13 of the upper sash 1l a rack 14 is rigidly secured, said rack being made to extend, preferably, from the lower rail of the said upper sash to the upper rail of the same, as best shown in Figs. 1 and 2. This rack may be constructed in any suitable or desired manner, and may consist, for instance, of a casting or a strip of thin material bent upon itself to form a series of teeth.

The upper sash is illustrated in Fig. 1 as provided at each side with a friction or clamping device 15, consisting of a piece of springwire coiled upon itself, one end of the wire being made to project in the direction of the rack. The coiled wire is held in contact with the inner face of each side rail of the upper sash by a pin 1G, passed through the same into the said rails, around which pin the coil is capable of revolving. When the end of the wire is carried downward to a horizontal position, the coils are made to expand and contact with the inner face of the windowframe in such manner as to rigidly secure the upper sash in any desired position. This is effected in order that the lower sash may be raised or lowered without moving the upper sash, in a manner hereinafter set forth. I desire it, however, to be distinctly understood that the spring-clamping devices 16 constitute no portion of this invention, as many other forms of devices accomplish the same end.

Upon the upper surface of the upper rail of the lower sash l2, at its center, a box or Casin g 17 is vertically secured, having an open outer end facing the rack. lVithin the casing 17 a spur-wheel 18 is journaled, capable of traveling upon t-he rack 14 when the lower sash is raised or lowered. Beneath the spurwheel 1S a rod 19 is held to revolve in suitable bearings, the said rod extending transversely of the casing from front to rear, and projecting beyond the latter point sufficiently to come in contact with a tooth upon the rack and terminating in a suitable handle or crankarm 20, whereby the body of the rod may be rotated or rocked at pleasure.

ln the bearing of the rod 19 a slot 2l is produced, and from the rod 10 a fixed dog or stop-pin 22 is upwardly projected through the said slot 2l, the said dog or stop-pin being capable of contact with one of the teeth of the spur-wheel 18 when the said pin or dog is brought to avertical position, as illustrated in dotted lines in Figs. 1 and 3 and in positive lines in Fig. 2. It will be readily observed that when the rod or rock-shaft 19 is manipulated to bring the stop-pin or dog to a horizontal position the spur-Wheel 1S is free to revolve, and that when either the up- IOO per or the lower sash is raised or lowered the wheel 18 will travel upon the rack 14, and whenit is desired to lock either sash in any desired position it is simply necessary to push forward the shaft or rod 19, turn the same, and bring the pin or dog 22 to a vertical p0- sition between two opposed teeth of the wheel. Thus the wheel is prevented from rotating, and the sashes are consequently held stationary. When the shaft is pushed forward to lock the end facing, the upper sash enters one of the spaces between the teeth of the rack, providing a lock itselfA before the dog is turned upward. By means of this construction should the pin journaling the spurwheel break the rock-shaft 19 will hold the window in the desired position until another is substituted.

Inmanipulating,` the sash it is convenient to elevate the sash with one hand and manipulatethe rock-shaft or rod 19 with the other.

I desire it to be understood that I do not coniine myself to the location of the rack upon the central railof a window, as it may be placed upon the side rail, in which event the casing 17 is placed opposite the rack upon the upper rail of the lower sash.

Having thus described my invention I claim as new an d desire to secu re by Letters Patentl. In a window-sash fastener, the combination, with the rack 14, of a spur-wheel 18 traveling upon said rack, a rock-shaft 19, journaled within a bearing provided with a slot 21, a pin or dog 22, carried upon said rock-shaft and working in the/ slot, the end of the shaft being provided with a suitable handle 20, whereby the rock-shaft may be turned to bring` the pin or. dog into engagement with the teeth of the spur-wheel, substantially as shown and described.

2. The combination, with the upper and lower sash of a window-frame and a rack vertically secured to the upper sash, of a casing secured to the lower sash, a spur-wheel journaled in the said casing in front of the, said rack, and a rock-shaft or rod capable of lateral movement and of sufficient length to contact with the teeth of the rack journaled below the spur-wheel and provided with an integral stop -pin or dog, said dog being adapted to contact with the teeth of the wheel, substantie lly as shown and described.
